FIG. 1 is a schematic diagram of a component architecture of a thermal management system 10 for an autopilot computing platform according to the present application. As shown in fig. 1, includes: a system controller 11, a cooling subsystem 12, and a heating subsystem 13.

And the system controller 11 is used for controlling the cooling subsystem 12 to work when the automatic driving computing platform 14 of the vehicle needs to be cooled, and controlling the heating subsystem 13 to work when the automatic driving computing platform 14 needs to be heated. How to determine whether cooling or heating of the autonomous computing platform 14 is required is not limited, and may be determined based on, for example, ambient temperature, etc.

A cooling subsystem 12 for liquid-cooled cooling of the autonomous computing platform 14.

A heating subsystem 13 for heating the autonomous computing platform 14.

It can be seen that, in the above-mentioned system embodiment, when the autopilot computing platform 14 needs to be cooled, the cooling subsystem 12 is controlled by the system controller 11, and the autopilot computing platform 14 is cooled by the cooling subsystem 12 in a liquid cooling manner, which has higher heat dissipation efficiency compared to an air cooling manner, so as to ensure normal operation of the autopilot computing platform 14 in a high temperature environment, and no additional noise is generated, thereby improving riding comfort, and the like.

FIG. 2 is a schematic diagram illustrating the operation of the thermal management system 10 of the present application. FIG. 3 is a schematic diagram of an arrangement of a thermal management system 10 according to the present application.

As shown in fig. 2 and 3, the cooling subsystem 12 may include: a water tank 121, a water pump 122, a radiator 123, a fan 124, and the like. The water tank 121, the water pump 122, the autopilot computing platform 14, the radiator 123, and the like may be connected by pipes to form a first circulation path.

Wherein, the water tank 121 is used for providing cooling liquid for the first circulation path. And a water pump 122 for powering the circulation of the coolant in the first circulation path. A radiator 123 for transferring heat generated by the autopilot computing platform 14 to the external ambient environment by heat exchange. And a fan 124 for assisting the heat sink 123 to dissipate heat. The specific components of the cooling liquid can be determined according to actual needs.

In addition, the cooling subsystem 12 may further include: a coolant temperature sensor 125, an ambient temperature sensor 126, and a coolant flow meter 127. A coolant temperature sensor 125, an ambient temperature sensor 126, and a coolant flow meter 127 may also be located on the first circulation path.

The coolant temperature sensor 125 is configured to obtain the coolant temperature at the water inlet and the water outlet of the automatic driving computing platform 14, and provide the coolant temperature to the system controller 11. And an ambient temperature sensor 126, configured to obtain ambient temperatures of the air inlet and the air outlet of the heat sink 123, and provide the ambient temperatures to the system controller 11. And a coolant flow meter 127 for acquiring a flow rate during circulation of the coolant and supplying the flow rate to the system controller 11. Accordingly, the system controller 11 can adjust the rotational speeds of the water pump 122 and the fan 124 based on information obtained from the coolant temperature sensor 125, the ambient temperature sensor 126, and the coolant flow meter 127.

That is, the cooling subsystem 12 may preferably be composed of a water tank 121, a water pump 122, a radiator 123, a fan 124, a coolant temperature sensor 125, an ambient temperature sensor 126, a coolant flow meter 127, etc., and the associated piping. The cooling subsystem 12 is independently controlled by the system controller 11, and is capable of adaptively adjusting the cooling (cooling) capacity according to the amount of heat generated by the autonomous computing platform 14.

The number of the water tanks 121 may be one or more, and typically one, for supplying the cooling liquid to the first circulation path. The water tank 121 may have a water inlet for connecting to the water inlet pipe of the first circulation path and a water outlet for connecting to the water outlet pipe of the first circulation path.

The water tank 121 may further have an exhaust port for filling the coolant and exhausting residual gas in the coolant during circulation of the coolant. That is to say, the cooling liquid can be filled into the water tank 121 through the exhaust port, and residual gas in the cooling liquid circulation process can be discharged through the exhaust port, so that no bubbles remain in the cooling liquid in the whole circulation path, and the cooling effect and the like are improved.

The water pumps 122 may also be referred to as electronic water pumps, and may be one or more, typically one, in number for powering the circulation of the coolant in the first circulation path. The water pump 122 may be disposed below the vehicle chassis and may be configured with a shock absorbing system that may be utilized to mitigate adverse effects from pump vibrations when the pump is powered up. The water pump 122 is in a speed-adjustable form, and can be adjusted by the system controller 11 according to actual requirements.

The heat sinks 123 may be one or more for transferring heat generated by the autopilot computing platform 14 to the external atmospheric environment via heat exchange. Preferably, the radiator 123 may be arranged/located at the engine compartment air intake of the vehicle to ensure that it can perform sufficient air convection to achieve good heat exchange. In addition, the radiator 123 may have an inlet and an outlet, and may have a plurality of load bearing support points so as to be rigidly connected to a rigid structural portion of the vehicle body.

Fig. 4 is a schematic diagram of an arrangement of the heat sink 123 according to the present application. As shown in fig. 4, 1231 indicates the outside air flow entering direction, 1232 indicates the vehicle body metal bracket, and 1230 indicates the radiator 123 and its fixing bracket.

The ambient temperature sensor 126 can be used to obtain the ambient temperature of the air inlet and the air outlet of the heat sink 123, and provide the ambient temperature to the system controller 11. The number of ambient temperature sensors 126 may be two or more, typically two. As shown in fig. 2 and 4, a first ambient temperature sensor 1261 and a second ambient temperature sensor 1262 may be included for respectively acquiring ambient temperatures of the air inlet and the air outlet of the heat sink 123 and providing the ambient temperatures to the system controller 11.

The fan 124, which may also be referred to as an electronic fan, may dissipate heat by rotating the auxiliary heat sink 123.

Coolant temperature sensors 125 may be utilized to obtain coolant temperatures at the water inlet and water outlet of the autopilot computing platform 14 and provide the coolant temperatures to the system controller 11. The number of the coolant temperature sensors 125 may be two or more, and is usually two. As shown in fig. 2 and 3, a first coolant temperature sensor 1251 and a second coolant temperature sensor 1252 may be included for obtaining coolant temperatures at the inlet and outlet of the autopilot computing platform 14, respectively, and providing them to the system controller 11.

The coolant flow meter 127 may be used to obtain the flow rate during the coolant circulation and provide it to the system controller 11. The number of the coolant flow meters 127 may be one or more, and usually one.

The system controller 11 can independently control the cooling subsystem 12, and adaptively adjust the rotation speeds of the water pump 122 and the fan 124 according to the information obtained from the cooling liquid temperature sensor 125, the ambient temperature sensor 126, and the cooling liquid flow meter 127, thereby implementing a closed-loop control of the entire cooling subsystem 12.

How the system controller 11 adjusts the rotation speeds of the water pump 122 and the fan 124 based on the acquired information is not limited. For example, the rotation speed of the water pump 122 and the rotation speed of the fan 124 corresponding to the acquired information may be determined according to a preset adjustment rule/adjustment formula, and adjusted accordingly.

In addition, the system Controller 11 may also communicate with the vehicle chassis by way of Controller Area Network (CAN) communication to obtain vehicle running speed information, and may adjust the rotation speeds of the water pump 122 and the fan 124 according to the information obtained from the coolant temperature sensor 125, the ambient temperature sensor 126, and the coolant flow meter 127 and the vehicle running speed.

That is, when adjusting the rotational speeds of the water pump 122 and the fan 124, the vehicle running speed may be further referenced, so that the entire thermal management system 10 is closed-loop controlled by a feedback signal of the vehicle running speed. How the rotation speeds of the water pump 122 and the fan 124 are adjusted with reference to the vehicle running speed is also not limited. For example, when the vehicle is traveling at a high speed, the rotation speed of the fan 124 may be appropriately reduced, and conversely, the rotation speed of the fan 124 may be appropriately increased.

As shown in fig. 2, the system controller 11 may also obtain feedback information of an Automatic Driving (AD) mode through CAN communication, and may operate the scheme described in the present application when the vehicle is in the AD mode.

Through the cooperation of the system controller 11 and the cooling subsystem 12, the autopilot computing platform 14 can be effectively cooled in a high-temperature environment (such as a high-temperature environment in summer) to ensure normal operation in the high-temperature environment, and the autopilot computing platform has a closed-loop adjusting function, and can adaptively adjust the refrigerating capacity of the system according to the temperature of the external environment.

The heater subsystem 13 may include a heater 131, etc., as shown in fig. 2 and 3.

The water tank 121, the water pump 122, the heater 131, and the autopilot computing platform 14 may form a second circulation path. As shown in fig. 2, the system controller 11 may switch from the first circulation path to the second circulation path by controlling a predetermined three-way valve 15 when it is necessary to control the operation of the heating subsystem 13, and may switch from the second circulation path to the first circulation path by controlling the three-way valve 15 when it is necessary to control the operation of the cooling subsystem 12.

The number of the heaters 131 may be one or more, and may be a Positive Temperature Coefficient (PTC) heater or other type of heater, and the adjustment control of the heating power may be performed. The heater 131 may be disposed at the vehicle chassis and may be rigidly connected to the vehicle body.

The system controller 11 can adaptively adjust the heating power of the heater 131 based on information obtained from the coolant temperature sensor 125, the ambient temperature sensor 126, and the coolant flow meter 127, thereby achieving closed-loop control of the entire heating subsystem 13. How the adjustment is made is likewise not limiting.

As shown in fig. 2, the coolant size cycle may be switched by a three-way valve (electronically controlled three-way valve) 15, and heater 131 may be deactivated when autonomous computing platform 14 is being cooled (i.e., when cooling subsystem 12 is active).

In the prior art, the automatic driving computing platform 14 cannot be normally started in a low-temperature environment due to the bottleneck restriction of the chip working temperature performance of the automatic driving computing platform 14. Through the mutual cooperation of the system controller 11 and the heating subsystem 13, the autopilot computing platform 14 can be quickly preheated in a low-temperature environment, so that the normal operation of the autopilot computing platform 14 in the low-temperature environment (such as the low-temperature environment in winter) is ensured, the low-temperature environment adaptability of the autopilot computing platform 14 is improved, a closed-loop adjusting function is provided, and the heating power of the heater 131 can be adaptively adjusted according to the temperature of the external environment.

FIG. 8 is a flowchart of an embodiment of a method for thermal management of an autopilot computing platform according to the present application. As shown in fig. 8, the following detailed implementation is included.

In step 801, the system controller determines that the autopilot computing platform of the vehicle needs to be cooled and controls the cooling subsystem to cool the autopilot computing platform in a liquid cooling manner.

In step 802, the system controller determines that the autonomous driving computing platform needs to be heated, and controls the heating subsystem to heat the autonomous driving computing platform, wherein the system controller, the cooling subsystem, and the heating subsystem are all located in a thermal management system configured for the autonomous driving computing platform.

The system controller can acquire the temperature of the cooling liquid at the water inlet and the water outlet of the automatic driving computing platform sent by the cooling liquid temperature sensor, the ambient temperature at the air inlet and the air outlet of the radiator sent by the ambient temperature sensor and the flow speed in the cooling liquid circulation process sent by the cooling liquid flowmeter, and adjust the rotating speeds of the water pump and the fan according to the acquired information.

The cooling liquid temperature sensor, the environment temperature sensor, the radiator, the cooling liquid flowmeter, the water pump and the fan are all positioned in the cooling subsystem; the water pump is used for providing power for the circulation of cooling liquid in the first circulation path, and the first circulation path is formed by connecting a water tank, the water pump, the automatic driving calculation platform and the radiator through pipelines; the water tank is positioned in the cooling subsystem and used for providing cooling liquid for the first circulation path; the radiator is used for transferring heat generated by the automatic driving computing platform to the external atmospheric environment through heat exchange; the fan is used for assisting the radiator in radiating.

The system controller may also obtain a vehicle travel speed, and adjust the rotational speed of the water pump and fan based on information obtained from the coolant temperature sensor, the ambient temperature sensor, and the coolant flow meter, and the vehicle travel speed.

In addition, the system controller may also adjust the heating power of the heater in the heating subsystem based on information obtained from the coolant temperature sensor, the ambient temperature sensor, and the coolant flow meter.

Accordingly, the system controller may switch from the first circulation path to the second circulation path by controlling a predetermined three-way valve when it is determined that the heating subsystem needs to be controlled to operate, and switch from the second circulation path to the first circulation path by controlling the three-way valve when it is determined that the cooling subsystem needs to be controlled to operate. The second circulation passage can be formed by connecting a water tank, a water pump, a heater and an automatic driving calculation platform through pipelines.

Furthermore, the system controller can also acquire the working states of all components in the cooling subsystem and the heating subsystem and send the working states to the monitoring display for real-time display and abnormal alarm.
